Measurement Category II is for measurements performed on
circuits directly connected to the electrical distribution system.
This category refers to local-level electrical distribution, such as
that provided by a standard wall outlet, for example, 115 V for
U.S. or 230 V for Europe.
Measurement Category III is for measurements performed in the
building installation at the distribution level. This category refers
to measurements on hard-wired hardware such as hardware in
fixed installations, distribution boards, and circuit breakers. Other
examples are wiring, including cables, bus bars, junction boxes,
switches, socket outlets in the fixed installation, and stationary
motors with permanent connections to fixed installations.
Caution
Do not connect the NI 9246 to signals or use
for measurements within Measurement Category IV.
